CVE-2025-4129
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAuthorization Bypass Through User-Controlled Key vulnerability in PAVO Inc. PAVO Pay allows Exploitation of Trusted Identifiers. This issue affects PAVO Pay: before 13.05.2025.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidencePAVO Pay before May 13, 2025 contains an authorization bypass vulnerability where the application trusts user-controlled keys (such as IDs or tokens in requests) without proper validation, allowing attackers to access or modify resources belonging to other users by manipulating these trusted identifiers.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify PAVO Pay versionLocate the installed version of PAVO Pay (check application metadata, about page, or configuration files) and compare it to any version released before May 13, 2025Affected if The installed version was released prior to May 13, 2025 and has not been patched since
-
Review API endpoints accepting user identifiersExamine application API endpoints, looking for parameters that accept user IDs, resource IDs, tokens, or session identifiers in request headers, query strings, or body dataAffected if The application accepts user-controlled identifiers (such as IDs or tokens) as parameters without requiring them to be server-side validated
-
Verify authorization logic for resource accessInspect server-side code or configuration that handles resource access requests. Check whether the application validates that the authenticated user owns or has permission to access the specific resource identified by user-supplied parametersAffected if The application trusts user-supplied identifiers without performing server-side ownership/permission verification before processing requests
-
Test for horizontal privilege escalationUsing two different test accounts, attempt to access or modify a resource belonging to one account by supplying that resource's identifier while authenticated as a different accountAffected if A user authenticated as Account A can access or modify resources belonging to Account B by manipulating identifiers in the request
The environment is affected if PAVO Pay version is before the May 13, 2025 patch AND the application accepts user-controlled identifiers (IDs/tokens) without server-side authorization validation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement server-side authorization checks that verify the current user has permission to access or modify the specific resource identified by user-supplied parameters before processing any request.
